  1. The Future of Space Travel Section 10.5

  2. Technologies • Since the 1950s we have – sent people to the moon, probes to planets, built the ISS. • As technologies improve so will space travel.

  3. Space Shuttle • Will be retired after 2010 • NASA is developing reusable launch vehicles. • The Ares rockets are scheduled to take people back to the moon and to Mars and other destinations.

  4. The Moon: A Testing Ground • NASA has a goal of sending astronauts to live and work on Mars. • The moon will be a test site and launching spot to head to Mars. • NASA has plans to send humans back to the moon in 2020. • Moon and Mars share properties – cold, covered in dust-like particles.

  5. Dangers of Exploring the Moon & Mars • Takes 4 days to get to the Moon, 6-10 months to get to Mars. • The fine layer of dust that covers the Moon and Mars may be up to 10m deep in places. • This dust can harm equipment but also irritate eyes, skin and lungs.

  6. Challenges of traveling to the Moon & Mars • Difficulties obtaining a constant supply of water, oxygen and food. • Protection from the cold and the Sun’s radiation (ultraviolet and X-Ray)

  7. Space Tourism • In 2009 the cost for space tourists was $30 million for 7 days! • Suborbital trips aboard specially built planes will take passengers to 100km above Earth and they will experience short bouts of weightlessness.. • Virgin Galactic charges $200,000 per trip

  8. Space Elevators? • There are scientists competing to develop the first elevator to space. • Would be tethered to a ship in the ocean and a counterweight in space • The climber would be powered by a laser • The cable would be 36000 km long • We currently do not have the technology

  9. Today’s Tasks • Read more about the Ares space crafts on page 434 • Pg. 437 #1, 2, 4, 6, 7, 10
